INTRODUCTION: I've put this eraser and 9 others (Pentel dust-gathering,
light-erasing, black and stein black, Boxy, Pilot Foam, Sakura Foam, Kokuyo
B/HB, Kokuyo 2B, Mars Plastic) through a rigorous and extensive series of 8
tests based on my application specifications (0.3mm Pentel Ain Stein B lead with
Rhodia paper). The tests were parallel (sustained) erasing, perpendicular
(instantaneous) erasing, smudge test (several perpendicular lines), large area
erasing, lead-dirty erasing, clumping, finger oil dirty erasing and eraser
shield compatibility. Of those tests, the main differences were highlighted in
the parallel, smudge, finger oil dirty and eraser shield tests.
REVIEW: This particular eraser, the Kokuyo B/HB, was amongst the best in all
test and I found it to be the all-around best performer. Sustained erasing left
an evenly and supremely faint line. Instantaneous erasing performance in the
smudge test was average, but reliable. Most distinguishing of all, this eraser
was utterly unaffected by skin oils and left the crispest, whitest patterns with
an eraser shield in a patch of lead-darkened paper.
CONCLUSION: For its extreme reliability and performance which, in my case,
surpassed even the venerable Mars Plastic in some cases, I give this eraser the
highest ratings as well as my personal recommendation, especially if your
operational parameters are similar to mine.
